ROLL-GRADING ACHINE.

' Specification of Letters letent. Patented July 21, 1914.,

Application filed April 7, l91-L Serial 86. 830,107.

To all whom it may concern:

Be it known that I, Join: C. BELL, a citi-. zen of the United States, residing at .12 Ann street, Harrison, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in B011 Grading Machines, fully described and represented in the following specification- -and the accompanying drawings, forming a 10. mm of thesame 4 i This invention relates to a means -for grading and separating rolls of different diameters which have been produced or I mixed in process of manufacture and from which it is desired 'to separate those of standard size.

By rte-duplicating certain parts of the apparatus, it may operate to grade therolls into a series 0f 'SlZBS and finally discard to a storage box the rolls which are unde sirahle because of cxcessiv'esize. The means for gaging the rolls consists of two heads having flanges projected toward-one another such flanges being formed with notches proportionedito pass rolls-of a given size, such rolls dropping-between the heads as they rotate and escaping through any ,of the notches upon the-lower sides of the headsand dropping into a receptacle' for. such gaged rolls. 'The rolls 1 which; are unable to pass through, the .notchesare taken from the periphery of the carrier by a rotating shifter, consisting of .disks with notches in the edges, which disks deliver the rolls to a succeeding carrier having slightly wider notches, through which a larger radcof rolls can pass and escape into al'di erent receptacle. The rolls unable topass through the notches of the 40 second carrier may he graded again or discarded as of excessive diameter.

A'shi-fter similar to that, just described .is preferably used to receive the rolls from the hopper and deliver them to-the' first gage-carrier, 'and also to take discarded rolls from the last gage-carrier and deliver them to'a storagebox. 4 s

, The invention will be understood byreference to the annexed drawing, in which Figure 1 is a plan of a grading machine embodying the improvements; and Fig. 2 v is a longitudinal section of the. same at the center line of Fig. 1. v I

' The machine is shown with side-frames'a and the heads-l of the gg ge-carrierare'shown a receptacle p carrier.

only, one'adapted to pass rolls e' of standhaving bearings b which shafts c are journaled for the gage-carriers, and. shafts d are jonrnaled for the. shifters. All the. shafts are geared together by gears .fian'd' intermediate gears f which cause all the shafts to rotate in the same,direction, to carr the rolls from a hopper g 'at one end of tie machine to a delivery-disk.li at'th, opposite end which discharges the discarded rolls into a storagebox .v The shifters are" shown in 1;.andp2, formed with disks having'notches kupon thc'margin adapte to receive rolls "e from. the hopper g, and to deliver them to the gagingjn'ws of the gage-carriers. The gztgecarriers are shown with two circular hoads'l spaced apart upon" the shaft (3 at asufii'cienti distance to let the gaged rollsd'rop freely. Y between such heads, and segments are projected inwardly fromlthe opposed feces ofthe'heads. The adjacent ends oi-th'e seg-'- nients form age-jaws n adjusted to 'gaige the ends of t e rolls andto pass those-of a given s ze. I

Dogs or movable jaws '0 are fixed-adjust;

ably upon the segments to project more or less across the space between their, ends, t'o vary such space in the jdesir'eddegree and.

such jaws may be adjusted to pass-{mus o.f any given size, by setting such a rollwithinthe space and securing the movable-jaw'in contact gvith the roll. The ends of the-seg- 'ment'sand the ends of the jaws are rounded upon both their inner and outer sides,; shown in Fig. 2,432) as to permit-it-he. rolls 3 to drop into the spaces when delivered there- 9G to by the shifter, and to through the gage formed by the jaw'fo 1f:' the rolls.are of i suitable diameter. The hopper is shown of the width required to carry rolls of n. certainlength, '98.-

adjusfted, so that thejawsqbearupon-the Y rolls quite near their en'ds thuspermittingthe rolls when the ass through the-jaws to fall-trcely between the heads and escape from the other sac-es in the segments into elow the rotating gage The drawing shows two gage-carriers I srd size, and the next adapted to pass rolls 6- which differ from the standard withina certain limit; but itisobvious that other gage-carriers maybe added to t hg 'series of two so ns to divide the rolls into a greafer 1 .1

number of "grades. The rolls c discarded by the last gage-carrier of the series, on account of their excessive size, are delivered to a storage-box and may, if desired, be afterward reduced to standard size by grinding or othersuitable means. Such storage-box might be placed below the dc? livery-side of the last shifter for the rolls to drop therefrom into the box, but to insure the positive delivery ofthe rolls from the shifter-disks, means for their removal is provided, consisting of two guides 8' and two plates It rotatable with asliaft 1' and slightly convex upon their adjacent sides.

{These plates are set even with the ends of the rolls and overlap the edges of the shifter-disks, and the rolls c carried by such disks are gradually crowded between the conical faces of the discharger which engages them with suflicicnt firmness'to lift them from the disks. A stripper inthe form of a delivery-board s is supported between th plates h to'strip the rolls therefrom and discharge them into the box i. The receptacles p" are \shown as drawers mounted in brackets t uponthe bed-plate a which supports the side-frames, of the machine.

It will be understood that thecssential feature .of the invention is the use of rotary gage-carriers having g'agingjaws through which rolls of definite slze. may drop, and

means for delivering the rolls automatically to such gage-carriers and removing therefrom the rolls which are above the desired gage. "The rotary gage-carrierixmay therefore be modified in construction without departing from the invention, provided it earheads with the ends of the rolls over the said spaces, whereby the rolls of standard size fall through the spaces between the heads and are collected in the receptacle.

2. Tn a roll-grading machine, the combi-- nation, with a rotary roll -gage-carrier having two'heads provided with roll-gages at different points upon their opposite faces, such gages having spaces permitting the paS- sage of the standard rolls, of a receptacle for the standard rolls, and means for deliw cring rolls for gaging, transverse to such heads, with their ends over the said notches, whereby the rolls of standard size fall through the gaging-spaces intothe space-between the heads and thence through spaces at the bottom of the heads, and are collected in the receptacle.
